Hoo boy...a quite amazingly done and veeery strange and cursed comm, depending on opinions by the talented Rex-equinox! If there was some Crack Ships...how about a Crack TF? Which isn't a shitpost or meme-like transformation but a genuine sort of effort to make an appealing transformation? Here we got Twilight Sparkle becoming the ever eponymous Thomas the Tank Engine, thanks to some conveniently placed magic shed buffers!

---

The metamorphosis of Twilight sparkle was about 90 percent complete, many minor things such as a headlamp being planted to the top right of her buffer beam and more red lines being painted were already under way. But her Cutie mark was moved to the middle side as the Coal bunker and cab had no room for such a mark like that.

Soon enough the Sparkling sigil would not last as suddenly it would distort and begin turning into a swirl of yellow and red before reforming into that of a large One, with a nice sunny yellow color trimmed with a good coat of red...It did belong to a certain number one engine.

Twilight also began to feel some tinges in her mind, she just said Bustling like it was some catchphrase to say when something shocking or bad happens as more knowledge began flowing into her mind...thankfully her mind was not being erased, merely being filled with knowledge about railway work, how to move and control her body and other general things about this world but the one thing to replace in her mind was her personality, feeling a bit more cheeky and hard working much like how she was always a bookworm working on her research.

For a moment she was a blue tank engine with a pony head on the front, which looked utterly ridiculous but it would not last long. Her magical horn would lose all sense of magic as it began to be rounded into a more cylindrical shape, the lines disappearing as the horn blackened to a more steely texture. The inside had hollowed out to allow residue smoke to flow out and to prevent it from clogging the boiler and causing problems. Some few rims had formed around the top base too as now it was a proud straight smokestack to funnel out that cloudy dust!

Feel free to fave, share around and comment your thoughts down below! Though...Derpibooru is probably gonna have my head for me with downvotes but i understand and that's ok. Not everyone's cup of tea and its their opinion. I hope this is an inspiring pic for many others for how the most unusual TFs can come from the most unexpected places.
